闪烁产额在液氩中的存在下的外部电场（\ensuremath{\le}6 kV/cm）的4%，9%，12%，和15%的能量为5.5，10，15，和20 MeV的He离子，分别增加。用5.305 MeV的\ensuremath{\alpha}粒子进行的比较研究发现，随着入射粒子的取向，闪烁增加的幅度几乎没有影响。闪烁的增加与可观察到的电荷收集的减少无关，这可能是由于入射粒子的轨道核中的淬灭减少。
Scintillation yields in liquid argon are found to increase in the presence of external electric fields (\ensuremath{\le}6 kV/cm) by 4%, 9%, 12%, and 15% for He ions with energies of 5.5, 10, 15, and 20 MeV, respectively. Comparative studies with \ensuremath{\alpha} particles of 5.305 MeV found very little effect on the magnitude of the scintillation increase with orientation of the incident particle. The increase in scintillation was not associated with an observable decrease in charge collected and it may be due to a decrease of quenching in the track core of the incident particle.
